2) High Pressure Control Lockout
• If the HPC opens three (3) times during the same call for unit operation, the ICC
will lockout the compressor to keep it from continuing to operate and flash a L” on
the dual 7-segment LEDs followed by a “29”.
Active Protection – Code L29 – Open high pressure control
IMPORTANT: This mode of active protection must be manually reset.
3) Locked Rotor
• The ICC will display a flashing “L” followed by a flashing “04” when a locked rotor
condition occurs.
Active Protection – Code L4 – Locked rotor
If the ICC detects the compressor has run less than 15 seconds before the pro-
tector tripped four (4) consecutive starts during the same call for unit operation,
the ICC will lockout the compressor to keep it from continuing to operate and flash
a “L” on the dual 7-segment LEDs followed by a “04”.
IMPORTANT: This mode of active protection must be manually reset.
4) Open Start Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “06” when an open start
circuit condition occurs.
Active Protection – Code L6 – Compressor open start circuit
If the ICC lockouts L6 and L6 detect current in the run circuit without current pre-
sent in the start circuit, the ICC will lockout the compressor to keep it from contin-
uing to operate and flash a “L” on the dual 7-segment LEDs followed by a “06”.
IMPORTANT: This mode of active protection must be manually reset.
5) Open Run Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “07” when an open start
circuit condition occurs.
